    No subwoofer bass when using carpc

    This is my setup:

    Epia M10000 (using the onboard soundcard)
    Sound directly goes into my pioneer 3600 (with one of those ip-bus hacks)
    Rear channel of the HU goes to the back of my car where it is connected to an amp. The amp is connected to a subwoofer.

    If I am playing cd's or radio the subwoofer's bass is loud and clear. When I am using the carpc I don't hear anything at all (just really low bass). This isn't really what I was hoping for.

    Why is the subwoofer suddenly really quiet when using the carpc?

    Thanks for tips and help.

    my first thought is to try plugging the subwoofer into the front outputs of the radio. I dont think this is the issue, but pioneer's have been funny about this in the past.

    the only other thing I can think of is that it is a computer hardware/software issue. I know others here have experienced it. I can't tell you if its as simple as turning the bass up within your sound card control panel, but you can try it.

    does the subwoofer still work, just at a lower level?

    Pioneer makes a input box that plugs in to your cd changer out put, this is the AUX feature on your cd player, thus eliminating the need for "hacks" and so on. It runs about $70. may improve your audio and fix your problem.

    just my 2 cants though.

    Get a better soundcard. I had only only moderate bass out of the pc with onboard sound,but when I added a SBLive, the bass was perfect. Little clearer sound too,and less interfearance.

    The sub works but the bass is really low level.

    I'll try switching to rear/front to see if there is any difference. I don't know how I can pump up the bass software wise since. Any input on this?

    As for the better soundcard part. I might try that, how are those usb cards? I can also try how my laptop reacts on it.

    The only thing I can think of right now, is that bus is mono... I've had one of these adapetors once on a different HU, and it was mono...
    Does your HU have amp outputs, or you you using high level inputs on your amp? If so, try switching the wires where you get your input of.

    I had the same problem with the same unit. Bt the 2600. Turned out the rca wasn't fully connected. From the pc to the aux input. It was half way on only. I pushed it on and bammm basss was rockn out. And the original aux plug isn't 70 bucks. Its caled the cdr b10 and its like 25 to 40 bucks. Maybe that's why u lost bass?? Cuz u used a home made one?

    yeah i have a homemade one atm i followed one of those tutorials just connected the l +/- and r +/- (while having an l and r indicates it's not mono :P).

    I am beginning to think that it is the aux input cable.
